EDK2-MSM port for Xiaomi Poco F5 (SM7475 / Marble) (WIP)

[Yuzuru10]

Description

What Has Been Done

1. Platform Bring-up

• Cloned and renamed SM8475 support to Platform/Xiaomi/sm7475/.
• Renamed and configured .dsc, .fdf, .dec, and other files for sm7475 & marble.

2. .dsc Configuration

• Updated:
  • PcdSystemMemorySize to match actual RAM.
  • PcdCoreCount, PcdClusterCount using cpuinfo.
  • Memory base addresses using iomem.
• Added:
  • SerialPortLib → QcomGeniSerialPortLib
  • UART base address: 0x894000

3. Apriori Drivers

Manually extracted and included crucial DXE drivers:

• SmemDxe, DalSysDxe, HwIODxe
• ChipInfoDxe, ClockDxe, PMICDxe, PlatformInfoDxe, etc.

4. Platform Library Modifications (Silicon/Qualcomm/sm7475/Library/)

• PlatformMemoryMapLib:
  • Adjusted MMIO/heap regions to avoid memory violations.
• PlatformPrePiLib:
  • Confirmed UART initialization is in place.
• marble.dec:
  • Added:

    gEfiMdePkgTokenSpaceGuid.PcdUartBaseAddress|UINT32|0x894000|0

I am assuming that adding these could be good because it can help other people even though it is very very WIP at right now.
